It provides 64KB of Flash program memory, 3.8KB of SRAM, and 1KB of data EEPROM in a 64-pin TQFP package. The device integrates a rich peripheral set including dual Enhanced EUSART modules with LIN and IrDA support, dual MSSP modules for SPI and I2C communication, a 12-channel 10-bit ADC, 6 PWM channels, and two analog comparators. The on-chip RTCC with 32kHz oscillator provides accurate timekeeping without external components. The Charge Time Measurement Unit (CTMU) enables capacitive touch sensing without external components. The device operates from 1.8V to 5.5V, making it compatible with a wide range of power supply configurations.","working_principle":"The PIC18F66K22 operates around the PIC18 8-bit CPU core with a hardware multiply unit for single-cycle 8x8 multiplication. The clock system supports multiple sources including an internal 64MHz oscillator (16MHz with 4x PLL), external crystals, and external clock. The XLP technology minimizes power consumption through optimized sleep modes with typical sleep currents under 20nA. The dual EUSART modules support asynchronous (UART) and synchronous (SPI\/LIN\/IrDA) communication with auto-baud detection. Each MSSP module implements full SPI master\/slave and I2C master\/slave modes with address masking for multi-master operation. The 10-bit ADC uses a successive approximation architecture with programmable acquisition time and can operate in sleep mode with the internal RC oscillator for reduced noise. The CTMU uses a constant current source to charge a capacitive element and measures the resulting voltage to determine capacitance changes for touch detection.","pin_description":"
